Modulus of Neighboring Rubbery Domain Strongly Impacts Local Glass Transition of Glassy Polymers

December 13, 2020

Physics PhD graduate student Yannic Gagnon and Professor Connie Roth have demonstrated that the local glass transition temperature Tg, the temperature at which the material locally transitions from an equilibrium liquid to a non-equilibrium solid glass, is strongly impacted by the modulus of a neighboring polymer domain. Polymer materials are often made of blends of … More Modulus of Neighboring Rubbery Domain Strongly Impacts Local Glass Transition of Glassy Polymers

Ground State Properties of the Diluted Sherrington-Kirkpatrick Spin Glass

December 4, 2020

By: Stefan Boettcher This paper adds a new perspective on the venerable Sherrington-Kirkpatrick (SK) spin glass model, which is a crucible of disorder and glassy behavior. It has applications not only in the physics of disordered materials, but also in AI (neural networks), brain function, combinatorial optimization, and machine learning, for example (see the book … More Ground State Properties of the Diluted Sherrington-Kirkpatrick Spin Glass

Prof. Urazhdin & collaborators solve the long-standing problem of nonlinear damping in magnetic film

August 11, 2020

Prof. Urazhdin and collaborators solve the long-standing problem of nonlinear damping in magnetic films. When the amplitude of oscillations in some dynamical systems become large, they start to experience nonlinear relaxation that suppresses large-amplitude dynamics. Among many manifestations of this adverse effect, it has prevented the development of efficient microwave oscillators based on magnetic materials. … More Prof. Urazhdin & collaborators solve the long-standing problem of nonlinear damping in magnetic film

Kim group shows how power law tail in replication lag time underlies bacterial persistence

August 11, 2020

Kim group shows that power law tail in replication lag time underlies bacterial persistence Persisters are antibiotic-tolerant cells that can evade antibiotic killing by ceasing replication.  They complicate antibiotic treatment, leading to treatment failure. Professor Minsu Kim and graduate student (now Ph.D.) Emrah Simsek quantitatively analyzed the non-replication periods of the persisters, and show that … More Kim group shows how power law tail in replication lag time underlies bacterial persistence

Prof. Nemenman reveals limits on precision of dynamic chemical sensing by biological cells.

August 11, 2020

Prof. Nemenman reveals limits on precision of dynamic chemical sensing by biological cells. Living systems sense chemicals in their environment when the latter bind to their surface receptors. Such binding is subject to the shot noise, which limits the sensing precision. How precise is such sensing? This storied question was asked for the first time … More Prof. Nemenman reveals limits on precision of dynamic chemical sensing by biological cells.
